Last month OnePlus released the OxygenOS 9.5.7 firmware update for its base 7 series smartphones. This was rolled out to both the European and Global variants of the device and has been completed. As the company looks to release its next update, you can download the stock kernel boot image for the update right here.
As I pointed out in the download post for the official update, the company ended up having some issues with the rollout. Sadly, there ended up being some sort of bug that affected a lot of devices. OnePlus halted it for a quick fix and then proceeded to fix it. The OnePlus 7 Pro received a similar fix but was pushed out via a separate update entirely.
This update had a heavy focus on the camera for the OnePlus 7 with improvements to the way the camera switches modes, the experience of autofocusing, the effect of stitching photos in Panorama Mode, and more. However, these improvements also made its way to other areas of the OnePlus 7 OxygenOS firmware as well.
So, if you are currently on OxygenOS 9.5.7 and are wanting to upgrade to the next version then you need to have an unmodified kernel file (aka the boot.img file). You can easily fix this by downloading the kernel for your version of Oxygen OS and then flashing it to the smartphone while it is in Fastboot Mode.
Download OxygenOS 9.5.7 Boot.img for the OnePlus 7
Once you have that downloaded, you’re going to want to rename it to something like “boot.img” (without quotation marks) for simplicity. From there, move or copy that file to the same folder as your ADB and Fastboot tools. Now you can boot the OnePlus 7 into Fastboot Mode and open a Command Prompt, Windows PowerShell, or a Terminal in that same folder.
fastboot flash boot boot.img
Connect the OnePlus 7 Pro to the PC and then execute the listed command above. That will overwrite your currently modified kernel (aka the boot image) and then replace it with the stock version. Now, presuming you haven’t made any other root modifications to the device, you can download that OTA update and install it.
If you have made other modifications (actual changes to the system, not apps that just need root access), then you’ll want to undo those changes before restoring the OxygenOS 9.5.10 kernel boot.img to the OnePlus 7 Pro.
